is secured thereto near its lowerend, said ring communicating through a pipe 9 with the air pressure supply, and each duct is provided with'a-port 10 leadingfrom the hollow ring to the interior of the duct. The air enterin the ducts throughthe ports 10 will mingle, with the gasolene therein and be thoroughl carbureted and will pass out through t e 'open upper ends of the ducts.

into the top of the carbureting chamber above the level of the gasolene and from thence through a pi e 11 to the system. The rin 8 is preferaby provided at intervals Wllil legs 12 whichrest upon the bottom of the carbureting chamber and support the cylinder a sufficient distance above said bottom to allow the gasolene to flow readily into the openlower ends of the ducts. l

The partitionwall 3 is provided W-itha valve casing 13 having a seat 14 and ports 15 leading into the gasolene chamber. A pipe 16 is mounted on said valve and extends upwardly through the top ofthe tank 2 and into a box 17 that is fitted within a pit or depression in the surface of the ground, preferably, and has a suitable cover 18 through which access may be had to the upper end of the pipe.

A rod 19 is provided within the pipe 16 and a plug 20 is secured to the lower end of saidrod and is exteriorly threaded to fit the interiorly threaded walls of the casing 13 and is rovided at its 'lower end with a socket into w 'ch 8. stopper 21 of yielding material,

preferably cork, 1sfitted and is adapted to ear on the seat 14 and close the ports a ainst the assa e of asolene therethrou h. g P o T g This construction a lows convenient removal of the plug and stopper for renewal or cleaning and also ermits access to the seat in case sand or se' lment of any kind collects thereon, which .would prevent the valve from closing tightly.

A ipe 22 leads from the valve casing 13 to ava ve casing 23 secured to the partition wall 3 but located below the same in the carbureting chamber. 24 through which the gasolen'e is discharged into the carburetin chamber.

A pipe 25 extends up through the top of the tank into the box 17. A rod 26 is pro-- vided in said ipe and a plug 27 is secured-t0 the lower en of said rod and is exteriorly threaded to fit within an interiorly threaded sleeve 28 that is arranged within the valve This valve has ports casing 23 and has pins 29 rojecting through tion with the plug .20., A seat 37 is formed in said casing for the said stopper and when the plug is screwed down into the sleeve the stopper will close the opening in the valve am prevent the passage of the gasolene through the ports 24 into the carbureting chamber. This plug-and its stopper may be removed for the purpose of cleaning or re pairs as described with reference to the dischar e valve in the gasolene storage chamber; In tie middle of the carbureting chamber above the cylinder 6 is a pipe 38 having a slot 39 in its wall through which connection is made by means of a coupling 40 u on the lever 33, and a rod 41 that 15 arrange within said pipe and extends up through into the box 17. The lower end of the pipe 38 has a slot 42 to permit the pipe to straddlea bar 43 mounted on a float 44 within the carbureting chamber. The lower end of the rod 4]. is threaded. to fit within a corres ondingly threaded portion of the bar 43 am when the rod is revolvedjas it may be by Q ening the box 17,, the float will be raised or owered on the rod according to the direction in which it is turned. This float controls the entrance of gasolene into the carburoting' chamber through the ports 24. The float is preferably made with considerable area and the pressure of the gasolene on its under surface will have a tendency to raise the float and its rod, rock the lever 33 and force the stopper 36 down upon its seat and shut oil the entrance of gasolenef The degree of this pressure can be regulated b i the adjustment of the float and this adjustment can be easily and accurately obtained without the necessity of having access directly to the carbureting chamber.

A pipe 45 leads into the top of the gasolene tank for filling purposes, and a branch pipe 46 preferably connects the pipe 45 with t e pipe38 to equalize the air pressure in the gasolene and carbureting chambers.

47'preferably extends down through the top of the tank to the bottom of the carbureting chamber so that a pump may be attacher thereto for the purpose of cleaning out the tank.

In operation, the floatis set in the de sired position to admit gasoleneinto'the carbureting tank, and the air flowing in through the ipe 9 and around the cylinder through the hollow ring 8, will enter the ducts and A pipe ends of the ducts and from thence to the 1. A carbureter comprising a wall having a series of ducts formed thereon and open at their upper and lower ends, the outer walls' of said ducts being provided with ports, and the lower portion of said ducts being normally immersed in a body of oil, and means outside said wall for delivering air under pressure to said ducts through said ports whereby it will be thoroughly carbureted upon its discharge from said ducts, substantially as. described.

2. The combination, with a wall having a series of ducts therein and open atthe top and bottom, and provided with ports in their walls, a hollow ring inclosing said wall and communicatin with said ports, a piperin and through which connected with said air under pressure is a mitted thereto, and the lower portions of said walls being normally immersed in gasolene whereby the air passing through said ducts and mingling with the oil therein will be carbureted, substantially as described.

3. A carbureter comprising a cylinder open at each end and having a series of ducts formed in its walls and also open at each end.

said ducts having ports in their outer side walls and the lower portion of said ducts being normally immersed in oil, andineans outside said wall and inclosing said cylinder for delivering air under pressure to said. port's whereby it will be carbureted in said ducts.

4. The combination, with a tank adapted to contain a supply of gasolene, of a wall suspended" therein and having a series of ducts with open upper and lower ends, the lower ends of said ducts being normally immersed in the oil in said tank, said ducts having ports in their outer walls, and means inclosing said wall for admitting air under pressure to said ports whereby it will be carbureted in said ducts.

5. The combination, with a tank having a horizontal partition dividing it into an upper storage or gasolene chamber and a lower carbureting chamber, of a wall'provided in said carbureting chamber and havin a series of vertical ducts formed therein 81K open at their upper and lower ends into said carbu reting chamber, and said ducts having ports in their outer walls, an air trunk inclosing the ducts and communicating with said ports, and with a source of air pressure, and the lower portion of said wall being immersed in gasolene'insaid chamber whereby the air flowing upwardly through said ducts will be carbureted, substantially as described.

6. The combination, with the tank, of a cylinder provided therein and open at each of said cylinder end and havin a series of vertical ducts vformed in its wa 1's and also open-at eachend and provided with ports in their outer walls,

sourcelof air supply, andthe lower portion eing normally immersed in gasolene in said tank, whereby the air flowing throughsaid ports and ducts will be carbureted, substantially as described.
